The National Hurricane Center (NHC) is the division of the United States' NOAA/National Weather Service responsible for tracking and predicting tropical weather systems between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific Ocean and the 31st parallel north in the northern Atlantic Ocean.
National Hurricane Center provides forecasts of the movement and strength of tropical weather systems and issues watches and warnings for the North Atlantic and the Eastern Pacific Ocean. NCEP Central Operations sustains and executes the operational suite of numerical analyses and forecast models and prepares NCEP products for dissemination.
In addition, at 1700 UTC during the hurricane season, a medium-range coordination call takes place between the Hydrometeorological Prediction Center and the National Hurricane Center to coordinate tropical cyclone placement on the medium-range pressure forecasts 6 and 7 days into the future for the northeast Pacific and Atlantic basins. Every ...
On July 1, 1956, a National Hurricane Information Center had become established in Miami, Florida which became a warehouse for all hurricane-related information from one office. [24] The Miami Hurricane Warning Office (HWO) was moved from Lindsey Hopkins Hotel to the Aviation Building 4 miles (6.4 km) to the northwest on July 1, 1958. [ 25 ]
The HWRF computer model is the operational backbone for hurricane track and intensity forecasts by the National Hurricane Center (NHC). [2] The model will use data from satellite observations, buoys, and reconnaissance aircraft, making it able to access more meteorological data than any other hurricane model before it. [2]
During 1990s the system was adapted by the National Hurricane Center (NHC) for use at the NHC, National Centers for Environmental Prediction and the Central Pacific Hurricane Center. [ 2 ] [ 4 ] This provided the NHC with a multitasking software environment which allowed them to improve efficiency and cut the time required to make a forecast by ...
The first statistical guidance used by the National Hurricane Center was the Hurricane Analog Technique (HURRAN), which was available in 1969. It used the newly developed North Atlantic tropical cyclone database to find storms with similar tracks. It then shifted their tracks through the storm's current path, and used location, direction and ...
After becoming a tropical depression, the system tracked slowly southwestward and eventually curved northwestward. The depression intensified into a tropical storm after three days and was named Rachel by the National Hurricane Center. Rachel continued to steadily strengthen, and peaked as a strong 65 mph (100 km/h) tropical storm on October 2.
